FIELD: agricultural engineering; interrow cultivation. ^ SUBSTANCE: proposed device contains frame with guides rigidly secured on frame for displacement of shanks of flat hoes in rotating joints. Drive hydraulic cylinders are installed on frame 1 on hinge joints relative to flat hoes from bringing the latter in and out of rows of plants. Hydraulic cylinders are hinge-connected to shanks of flat hoes. Rotating joints include splined pairs: body, post two axle-shafts used for rotation of bearings rigidly connected with housing. Shanks of flat hoes are connected with hydraulic distributors through feedback and hydraulic lines. Plant detectors connected with pull-back springs are installed on axle of hydraulic distributor spool. Pressure and drain spaces of hydraulic distributors are connected by hydraulic lines with hydraulic distributor of tractor. ^ EFFECT: decreased uncultivated zone around trunks of plants, increased service life and improved reliability of device, provision of stabilization of movement along rows between plants. |
